IMPROVEMENT IN MACHINES FORDISINTEGRATING FABRICS.

Specification forming part of Letters Patent No, 143,290, dated September 30, 1373; application filed July 23, 1873.

CASE B.

smaller gear, 0, fixed on the shaft of the lower To all whom it may concern:

Be it known that I, Mosns MARSHALL, of Lowell, of the county of Middlesex and State of Massachusetts, have invented a new and useful Machine for Breaking up either the Warp or the Weft Threads of Oloth; andI do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 a front elevation, Fig. '3 a side view,'and Fig. 4 a longitudinal section of it.

In such drawings, A and B represent two I cylinders, each of which is grooved transversely with numerous grooves parallel to each other, and extended entirely around the cylinder. One of these cylinders is arranged over the other, the projections formed by the grooves of each cylinder being extended into the grooves ofv the other, as shown more particularly in Fig. 5, which is a longitudinal section of the two cylinders and their sectoral clearers. These grooved cylinders are arranged within a supporting-frame, O, in manner as shown, and in advance of an endless feeding-apron, D, extending about rollers D E. The upper part of the apron passes over and upon a platform, F, and between two parallel guides, at a, erected thereon. There are pivoted in such guides two rollers, 11 I), having their journals arrangedin vertical slots in the guides. On the shaft of the driving-roller of y the endless apron is a spur-gear, c, that engages with a gear, d, fixed upon the shaft of the upper of the two grooved cylinders A B.

The said gear d also engages with another but fithermvo cylinders A B, such shaft having upon its otherend a larger gear, f, that engages with a piniem g, carried by a drivingshaft, h, all being arrangedas shown. Fur thermore, there is appliedtothe breakingcylinders A B two vibratory clearers," G H,

one being arranged over the upper of said cylinders and the other below the lower of them. Each of the clearers is formed or provided with ribs to enter the grooves of its cylinder, in manner as shown. Each clearer is supported by two sectoral arms, 1' i or k k, which turn freely on the shaft of the grooved cylinder of such clearer. These arms are geared together and to other arms, I l, in manner as represented in Fig. 2, and more particularly in Fig. 6, which is a vertical section of the arms on one side of the machine. The arms I Z project from a rock-shaft, m, arranged and provided with a crank, it, in manner as shown. From the wrist of the said crank a connecting-rod, 0, extends to the wrist of a pinion, p, fixed upon a shaft, q, and engaging with a spurgear, 1", fixed upon the driving-shaft.

I would remark that the lower of the two grooved cylinders, while the machine is in use, should be revolved faster than the upper roller, in order for it to operate to the best advantage. On turning the driving-shaft, not only will the two grooved cylinders be simultaneously revolved, but the endless apron will also be put in movement, and each of the clearers will be moved transversely forward and backward upon or against its cylinder.

If, while the machine is in movement, a piece of cloth having its warp of wool and its weft of cotton threads or yarns be laid upon the endless apron so that the warps may be parallel, or about so, to either edge of such apron, such piece will be introduced into the bite of the two grooved cylinders, the piece, during its passage to the said cylinders, being smoothed out by the rollers directly over the apron. On passing between the two cylinders, each of the Weft-threads will be so strained as to be cut or broken up into very short pieces, and will be loosened in the warps, which will remain uncut or unbroken, the whole being so as to enable the said warps, by other and proper machinery, to be readily separated from the broken wefts and untwisted and prepared for being again used for any of the purposes for which wool is generally employed in the arts. V

The clearers operate to clear the grooves of the cylinders of the warps and broken wefts, and cause them to be properly delivered from the machine. The clearersmay be stationary;

butit'fisfpreferab'le "110' haveth'em' movable, as

describedfiwhile the" cylinders are in revolu tion. So the grooves of the cylinders may be formed so as to cause the cy1inders, whi1e operating together, to out each of the weftthreads, rather thanbreak'it into numerous short pieces; but it is preferableto haife 's'deh" cylinders break the thread,='asin such case they are not liable to out or break the warps.

This machine may be used to cut or break 1 the warp-threads and'le'ave theweft threa'ds entire, provided the cloth be properly presented' to the IOIlI'S ViZt iSQ that the Wei-ts may be at right angles therewith:

I claim- For the purpose set forth, the machine substantially as described, consisting of the two grooved-cylinders A B, the vibratory clearers G H; and thefeeding-apronD, combined and operating substantially as specified.
